Coaxial connector with ingress reduction shielding

A coaxial connector comprising:

• a metallic waveguide configured to shield the internals of a connector body from the ingress of radio frequency signals;
• a waveguide aperture having a diameter greater than an outer diameter of a mating connector center conductor;
• a first electrical insulator for covering a waveguide surface subject to contact by the mating connector center conductor during its alignment with and insertion in the waveguide aperture;
• a first electrical insulator through hole having a diameter greater than an outer diameter of the mating connector center conductor;
• and,
• the mating connector center conductor for passing through the first electrical insulator through hole and the waveguide aperture.
